  • an EEC 501 when an EEC 501 obtains vECS address information (e.g., as aforementioned by referring to the FIG. 2 , when the UE obtains vECS information while establishing a PDU session for the VPLMN or obtains vECS information from an hECS), the EEC 501 may transmit, to a vECS 507, a service provisioning request message to use an edge computing service in the VPLMN.
  • the service provisioning request message may include an HPLMN ID, hECS information (an address, an identifier, a provider ID (ECSP ID), etc.), an EEC ID, a UE ID, etc.
  • the vECS 507 may identify whether there is edge computing service agreement (including roaming agreement) between a PLMN operator identified with the HPLMN ID and a vECS provider (ECSP) to identify whether it is possible to provide a service to the EEC. Furthermore, in operation 520, the vECS 507 may use the hECS information received from the EEC 501 to transmit an EEC information request message to the hECS 503 to identify information about the EEC.

  • the hECS 503 may perform a procedure of identifying an EEC corresponding to the information included in the EEC information request message received from the vECS 507. For example, the hECS 503 may provide the EEC information (the EEC ID, the UE ID, etc.) received from the vECS 507 to an edge computing service subscriber database 505, and obtain information about a UE subscriber for the EEC (e.g., whether it is possible to provide an edge computing roaming service for the EEC through the VPLMN and the vECS).
  • EEC information the EEC ID, the UE ID, etc.
  • the hECS 503 may transmit, to the vECS, a response message to the EEC information request of operation 520.
  • the message may include information about whether it is possible to provide the edge computing service to the EEC.
  • the vECS 507 may determine whether it is possible to provide the edge computing service for the EEC through the EEC information request response message received from the hECS 503. When it is possible to provide the edge computing service for the EEC, the vECS 507 may provide the EEC 501 with information about an EES available through the VPLMN in operation 550.
  • the information about the EES may include an EES ID, EES address information, a DNN or network slice information required for establishing a PDU session to access the EES, etc.
